I love the 7.3 but have seen too many trannys replaced to consider that platform for serious towing. If someone had replaced/beefed up (there are some excellent aftermarket 'bulletproof' tranny rebuilds available) the trans previously however.....
The 6.0L in the GM may not have all the torque the 7.3L Excursion can lay down but even loaded to the limit and beyond, you'll have a tough time breaking it. With a rear spring upgrade (helpers, air springs, timbrens, etc.), and good tranny cooling, I'd expect the 8-Bolt 'burbs (I like it!) to be just as capable as the Excursion.
FWIW: We had a dealership truck, '03 Silverado 2500HD with the 6.0L/4L80E and towed JD 110 TLB's around, 5000 series tractors and many many smaller tractors plus the Ready To Mow trailer (about 5-6000lbs loaded) occasionally too. At about 53,000 mile the trans gave up. The tech that tore it down said it wasn't the constant heavy towing (110 TLB with loaded tires & acc was pushing 10,000lbs + the trailer) that killed it. It was the Gen Mgr driving the empty truck like a rented mule and not stopping before changing direction. The rear planetary gearset had grenaded. Last I heard the truck was doing fine at 150K+ and if I know that dealership, the truck's maintenance has most likely been seriously neglected.
